Question

5 would calcium carbonate dissolve in water? (a) a yes, it is soluble in water b no, it is not soluble in water (b) which statement below is evidence that supports the claim chemical reactions could be happening between the calcium carbonate and acid rain causing the taj mahal to break apart. a the acid rain can form from certain pollutants in the air. b calcium nitrate is soluble in water so the marble will dissolve when exposed to water. c calcium carbonate is not soluble in water so the marble will not dissolve when exposed to water.

Explanation:

• For part (a): According to solubility rules in chemistry, calcium carbonate (\(CaCO_3\)) is generally insoluble in water.
• For part (b): If calcium carbonate is not soluble in water (as established in part (a)), but there is damage (like breaking apart) due to acid - rain (which is acidic), it implies a chemical reaction (not simple dissolution) is occurring. Option C provides a baseline (no dissolution in water) which makes the chemical reaction (with acid - rain) a more plausible explanation for the breaking apart.

Answer:

(a) B. No, it is not soluble in water
(b) C. Calcium carbonate is not soluble in water so the marble will not dissolve when exposed to water.
